130 values out of 3,000 is 4.3% of the table. If you have narrow records with,

the problem is that string parsing is best done in python, but as far as I

A simple example shows that EXECUTE does indeed work with DDL:
CREATE TABLE foo (col1 integer);
CREATE FUNCTION
If you need to use a double quote inside a VB string, you have to write two double quotes (double double quotes!),
so your command will be something like:
select * from
public.Customers

Sure. Just set up psql with a SQL script containing your task using a

The psql utility will accept a command file as a parameter.
PostgreSQL has functions rather than stored procedures, but it works out
about the same.
You could also put a bunch of SQL commands that you want to run

Actually, I see you can't store/retrieve blobs remotely, which is
a non-starter. So the remaining choices seem to be bytea vs.
storing only metadata and keeping the images elsewhere
